    120 gr gmx

    Hi
    Is anybody out there using 120 gr Gmx in 6.5 x 55 that has any loads they'd be willing to share, particularily using Vit N160. Just about to start trying these and looking for any advice going. They'll be used in a sako 85.

    I use 46g of N160 with 120g Sierra Prohunter's or Speer Hotcore, both shoot to the same point of aim. I have been up to 48g of N160 but just got more "bang" and "kick" rather than any real improvement in down range and knockdown performance.

    Thanks Duncan I'm wondering whether the Gmx all copper head will make any difference but am struggling to find load info.

    I struggle to get a decent group with .30 calibre version, hope you have better luck than me.

    Just back from the range shooting a tikka T3 in 6.5x55 so roughly the same barrels. Using N160 the node points were at 45.8 and 49.8. Chronoed rounds 45.8 was 2350 and therefore not deer legal as energy was 1300ish lbft. The higher load was 2700 therefore giving 1885 Lbft and legal. Played around with COAL starting at 2.355 (hornady comparator) and found one hole group at 2.345. This Is a long way off the lands but they cope with the jump. I know Barnes always says they like to jump so may be useful. It is worth playing around with things as they can work. The data for N160 is 45.8gr-50.7gr so you have a large range. From my experience it is worth checking they have enough energy to be legal for deer.

    hope this helps,

    More proof that loading to the lands (or close to) is not necessary for good accuracy. My 7-08 tikka is shooting half inch with regularity using a 120 grn Game Pro seated to the base of the neck.~Muir

    Hi Blitzking i'm certainly finding them challenging as well. Best so far is 1" at 100 and still expanding considerably at 150. Just made another selection of batches going a bit slower but not going to get a chance to test for a couple of weeks now. When Hornady stopped the 140 sp I thought it would be a good time to try these Gmx but not so sure now.
